A series of EPA studies of environmental hazards problems associated with energy emissions leads to the conclusion that the previously developed powerful ultrasonic devices and systems with the use of electronic components and low degree of integration could have been potentially dangerous to human health. The updated concept of using ultrasonic devices is aiming at reducing the possible harmful radiation related devices, firstly, through the reduction in unit capacity of ultrasonic devices and the choice of technology-specific ultrasound parameters sufficient to implement the process. Secondly, an improvement in safety is achieved by using modern element bases and the performing the corresponding changes in circuit design of ultrasonic generators and waveguide design, application of modern schemes of automatic stabilisation modes and emergency protection. It has been experimentally proved that the number of multi-function devices can be designed not to cause harmful emissions and energy fields – a decent example of Hilsonic can be considered – the company focusing on production of complicated ultrasonic cleaner equipment; the technological processes and approaches practised here ensure unparalleled safety of the ready products.

The fact should be also underlined that the process of ultrasonic technologies integration in many industries, such as processing of raw materials, is a factor that significantly reduces the supply to the process of operation of other energy flows, and thermal energy in particular. The environmental benefits of this need no proof. Finally, the intensification of many processes, for example in the field of ultrasound extraction reduces and total exclusion from the reaction mass number of extract-ants recognised as harmful to the environment. For example, with the ultrasonic extraction of oil from sea buckthorn pulp withdrawal of CFCs from the process becomes real.

Thus, the ultrasound technology with hardware-based multi-function low-power generators in many respects can satisfy the requirements of salvage, resource-saving, environmentally friendly processes and provide a more efficient compared to the traditional methods use of natural resources.

However, a final conclusion about the environmental safety of ultrasound should be done as long as the factors of its direct effect on living organisms are considered and a confirmation received that ultrasound systems do not break the flow of information of natural systems and do not create emissions dangerous for the existence, development, reproduction and adaptation of living organisms. Therefore, the analysis of environmental security should continue to study the factors that determine the risk of the use of ultrasound in direct contact with the person. This task is part of the more general problem of analysing the effectiveness of technical solutions to meet the requirements of environmental protection and environmental management at the stages of design and testing, because at the present time, science has become a productive force, resulting in the emergence of a new source of harmful effects on the environment – scientific – technical activities of man. One of the problems that must be addressed in the development of technical solutions, is the problem of the classification of the possible adverse effects on the severity and irreversibility, and, accordingly, the necessary measures should be taken to prevent them.

One of the core advantages of WOM-marketing is versatility. This method can work perfectly for companies of all sizes, regardless of the type of business: whether you are a transnational corporation with hundreds of offices around the world, or a small hair salon, opened last Monday. Surprisingly for many, location is also not that crucial. However, of course there is a ‘but’.

This ‘but’ is the quality of your product and service. If it is fairly good and the customers are satisfied after the interaction with your company, their ‘words’ will work for you. And if not, it will level all the advertising of your brand. If you offer the quality that leaves much to be desired, WOM marketing as a method of advertising does not suit you. You will not just have to deal with a couple of unhappy customers, the problem to be solved may be truly huge, and the risk of provoking a real reputational collapse will grow.

Quality and trust are the foundational stones of WOM-marketing. Many marketers even argue that in this case, the word of mouth can be a ‘no-investment’ marketing weapon. If you are a good company, you will exponentially increase the recommendations should only give the first impetus to the Internet.

But is it really so? If you believe that WOM marketing may demand no resources at some point of time, then it’s the wrong attitude. Undoubtedly, there are examples where without any effort the company became popular and discussed, but these cases demand unmatched marketing brilliance and good luck. You may want to try getting in touch with industry experts, like HTP Digital, a far-famed b2b digital marketing famous for its range of successful marketing project for hi-tech companies. In other cases, you will inevitably have to invest in WOM-marketing.

With traditional marketing channels, there is a linear relationship between expenditure and return on investment. You get a certain number of requests for a particular value, for example, each $1 million of additional advertising investments generates a certain increase percentage in sales.

In case of word-of-mouth marketing things are different. Initially, the process will remind a J-curve, quite linear up to a point, rather than having a more exponential form. However, if good practices are taken advantage of, once the marketing campaign ends, the result will continue to grow and the amount of investments will decrease. At this point starts the organic sundresses marketing, which received a boost from paid. The effect of the campaign, there is still a long time after its completion – the conversation continues by inertia, and ultimately J-curve takes the form of the S-curve.

There’s a variety of different methods of word of mouth marketing, both online and offline. Internet plays a vital role in WOM, but it is not that overwhelming. This is where a trap for marketers is hidden – hundreds of specialists want to see WOM-marketing in action to evaluate its effect. But often they allocate too small budgets, collide with a lack of time and have unprecedentedly high expectations. And, with this approach, they are doomed to failure.
